Abstract
Abstract The effect of treatment of mice with tryptophol (TOL), a neutral metabolite of tryptophan, on drug-induced convulsion was studied. TOL effectively suppressed both pentylenetetrazol and picrotoxin induced convulsion. Diphenylhydantoin (DPH), a potent inhibitor of brain aldehyde reductase, significantly reduced the anticonvulsant effect of TOL, however, TOL level in brain of DPH-treated mice was rather higher than that of control one. These results strongly suggest that the manifestation of the anticonvulsant effect of TOL requires the conversion of TOL to its active metabolite, indoleacetaldehyde.
